Frivolous

Of minimal importance; legally worthless.

A frivolous suit is one without any legal merit. In some cases, such an action might be brought in bad faith for the purpose of harrassing the defendant. In such a case, the individual bringing the frivolous suit might be liable for damages for MALICIOUS PROSECUTION.

A frivolous appeal is one that is completely lacking merit, since no review able question has been raised therein.
